PAUL. w. ERN$BERGE.R, or A134,, OHIQ BAG HOLDER Application filed May a,1931. Serial No. 535,434.,

invention has for its object to provide a means for readily securing ain PO31: tion for the purpose of filling the bag with a material andwherein the securing means 5 may be readily operated to release the bagwhen the bag has been filled. The invention is particularly adapted foruse in connection with material dispensing machines or devices wherematerial is discharged into flexible con,-

10 tainers, such as cloth bags. It finds advanr tageous use in grainelevators where the gra n is directed from chutes into bags. 1

The bag holders embodying my invention are so formed that thebagsmay'bereadily placed. in posit-ion on the end of. the chute and closedabout the chute, and when the bags have been filled they are readilydisconnected from the end or: the chute Without raising the bags.

The invention maybe contained in structures of different forms and, toillustrate a practical application of the invention, I have selected asan exampl of such structures, a

bag holding device particularly adaptable .or spouts of different formsfor directing material of different kinds into containers that may besupported on the ends of the spouts.

The particular construction selected as an example is shown in theaccompanying draw- 39 in gs and described hereinafter.

Fig". 1 of the drawings illustrates a perspective view of the bagholding device and illustrates the chute and the bag connected to theend of the chute by the holding device. Fig. 2 illustrates a perspectiveview of the holding end of the chute by the holding device. Fig. 3illustrates aview of a vertical section ofthe device and a part of thechute. Fig.4 illustrates a vertical section of the device taken on aplane located at right angles to the plane of the section shown in Fig.3.

In the particular form of construction shown in the drawings, a chute 1,which is ordinarily supported from the rafters or upper structure of anelevator building, depends to a point in proximity to the floor or to aplatform. The empty bags are connected to the chute l to receive thegrain from the chute. The lower end of the chute 1 is provided With apair of plates 2 that are secured to opposite sides of the chute. If thechute 1. has, a. Width less than thatof the plates, a suitablfehlqck 3maybe secured on one of the sides ofthe huteto, pr vi a sui ab supp t01,111". dation for the plates 2. The lower edges of -55 the plates 2are providedwith shells 4, oblong: in form, an pr d d th op ni g 5- A Pof emb rs 6 y b a lv movable relative to the plates 2; The members ,6are preferably T-shaped and maybereferred to 59 as T-b rs- Th oss pa tso he Trba s 6 e ocated w n t e' h Th T- ars, Prefe bly, ub tan a y fit te i er rofthe shells 4. e re p d w t arsedvends wh ch fit the en p rtons o t h s 9 All guiding movements of the cross parts 'Z-of th -bar hehank 0f h T-be sier members 6 pr t u hr ug the per Wa s of the h lls 4iand a e onnect d w t Maeans f ra ing and qv r nse he T r Bee" ansupportin p n eq rin 9 are nn ted i he nds of 'c o mem ro the T- ara1idextend through the openings 5 whereby ver? tical movements of themembers 6 raise and lower the pins 9 and consequently cause the 15 Pi PMe 1 hr h h p ni or are owered to locate the pointedends of the pins 9Within the shells 4c.

The T-bars or members 6. are raised and lowered by a pair of camv bars12, The .can so bars 12 are forme d of flat metal bars that areconnected together by a handle 13 and are supported for sliding movementby the plates 2- T e bar .12 a p ov ed W h P a lel slots 14 and slots 15that are located interme 3 5 ie s he Slots T e Para l s ot liar inclinedto the lower edges of the bars .12 and the slots 15 are, preferably,located intermediate the slots 14. Each slot 15, in each bar 1 2 rs p iea yi m. the :l -u ie 9f as oneslot lsto the upper end ofthejother slotlit. The lower end portions 16 9f the slots 14: and the upper endportions 17 of the slots 1 5 extend parallel to the upper and loweredges of the bars 1-2 and, hence, the slots and lfi 13? are angularform.- a I i The bars 12am connected to the plates Zby means of pins 18.If desired, suitable wash,-

r and atter esy e locat i h ende .oiihe pin .0 ma n a he a s 2 n r sitee 1 When the bars 12 are moved lengthwise they are raised or lowered,depending on the direction'of their movement, by reason of the movementof the edges of the slots 14- along the pins 18. The members 6 areconnected to the bars 12 and are raised and lowered with the raising andlowering of thebars 12, to raise and lower the pins 9 and to cause themto project from the shells 4 or be receded in the shells4. I c e In theparticular form of construction shown, the T-bars or members 6 areconnected to the bars 12 by means of pins 20 that extend through theslots 15. Theupper ends of the T-barsare guided in their verticalmovements by links 21 which are pivotally connected to the pins 20 andto one set of the pins 18. The links 21 thus coact with the innersurfaces ofthe shells 4 to guide the T- bars or members 6 in theirreciprocatory movements produced by the sliding movements'of the cambars 12. Since the slots 15 operate on the pins 20 to raise and lowerthe T'bars, while the bars 12 are raised and lowered by the cam slots14, the movement of the T bars-or members 6 is equal'to the sum of theheights of any one of theslots 14 and the height of any one of the slots15. This is due to the fact that the bars 12 are raised and lowered whenmoved longitudinally and, by reason of the slope of the slots 15, theT-bars are moved relative to the bars 12. This affords extendedmovements of the pins and consequently enables the use of relativelylong pins as comparedto the width of the bars 12. b

When it is desired to fill a bag, the handle 13 is pressed towards thechute which opera atesto raise the bars 12 by the movement of the edgesof the slots 14 along the pins '18 and to raise the members 6 and thepins 9 connected to the members 6 by, not only the raising movement ofthe bars 12, but also by reason of the slots 15 which move the membersupwardly relative to the bars 12. This locates the points of the pins 9well above 7 the tops of the shells 4 The edge of theopen end of the bagis then forced on the pins and at the same time is tightly drawn aroundI the chute. The cloth of the bag is punctured by the pinswhich hold thebag in position on the; end. of the chute. The open ends of the bags areinvariably much larger than the chute and the extra amount of the-bagmaterial at the openend may be folded over and secured to anotherof thepins. Thus the interior of the bag is completely closed and the escapeof dust fron ithe grain is prevented.

into the shells 4 and allows the bag to drop by the weight of thematerial in theibag from the end of the chute.

I claim: 7 1. In a bag holder,;a chute, a pair of plates secured toopposite sides of the chute, a pair of connected slidable bars havingcam slots and pins extending through one set of the slots for shiftablysupporting the bars for 7 horizontal and vertical movements of the bars,a pair of shells connected to the plates, 7

a pair of T-bars supported in the shells and having pointed pinsconnected to the ends of the cross members of the T-bars and extendingthrough the tops of the shells for engaging the ends of bags, the T-barshaving i:

shank parts extending through the tops of the shells, pins extendingthrough another set of slots for connecting the upper ends of the shanksof the T-bars to the slidable bars, and

links connecting the upper ends of the shanks i r to one set of thefirst named pins for raising and lowering the pointed pins in the shellsto release the bags, the T-bars guided by the links and the shells intheir reciprocatory movements produced by the slidable bars.

2. In a bag holder, a chute, a pair of slidable bars located on oppositesides of the chute, a handle interconnecting the slidable bars, the barshaving cam slots, pins extending through one of the slots for shiftablysupporting the bars on the end of the chute for horizontal and verticalmovements of the bars, a pair of members connected to the end of thechute below the bars, a pair of T-bars having pointed pins connected tothe ends of the'cross parts of the T-bars and extending through themembers and adapted to engage the ends of the bags, the shanks of theT-bars extending through the said members, pins extending throughanother set of the slots for connecting the upper ends of the shanks of"the T-bars to the slidable bars, links connecting'the upper ends of theshanks for directing the raising and lowering movements 0] the T-bars bythe last named slots to release if.

the bags from the pointed pins.

In witness whereof I have hereuntosignezl.

my name to this specification.
